Abstract

Two mononuclear complexes, [Ni(acac)2]·0.5CH3OH (1) and[Co(acac)2NO3]·2H2O (2) (acac = pentane-2,4-dione), have been synthesized andcharacterized by single crystal X-ray analysis. Complex 1 crystallizes in the monoclinicspace group P21/c with a = 9.295(4), b = 11.450(5), c = 12.974(6) å, V = 1379.1(11) å3,β = 92.854(7), and Z = 4. Complex 2 crystallizes in the triclinic space group P(-1) with a= 8.153(9), b = 9.925(11), c = 10.355(12), V = 746.3(15) å3, α = 70.530(16), β =71.154(15), γ = 80.698(16) and Z = 2. Complex 1 has a one-dimensional chain-likestructure, which is extended by weak hydrogen contacts, while complex 2 shows a three–dimensional network structure.
